Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
In the engineering application of the present stage, the antenna and the filter are often designed separately, and an additional external matching circuit is designed to connect and debug the antenna and the filter.
Therefore, in order to reduce the loss and achieve miniaturization, the inventors considered combining the filter characteristics with the antenna to achieve the filter characteristics of the antenna. The filter and the antenna are directly cascaded to carry out integrated design so as to reduce unnecessary external matching circuits, thereby reducing the matching loss, but the insertion loss of the filter still exists.
To further reduce insertion loss, the inventors contemplate a filter antenna fusion design that allows the antenna to have both radiating and filtering functions without additional insertion loss.
In the filter antenna fusion design, the antenna is used as the last-order resonator resonance of the filter to realize the filtering function, and the transmission mode of the antenna is changed by changing the antenna structure, such as etching gaps, adding metal through holes, or adding metamaterial structures, so as to generate transmission zero points, thereby realizing the filtering function.
Referring to fig. 1, fig. 1 is a schematic diagram of an antenna unit according to an embodiment of the present application. The antenna element is used as an integral part of the filter antenna, and it should be noted that the filter antenna may include a plurality of antenna elements, only one of which is shown in fig. 1 for convenience of illustration.
As shown in fig. 1, the antenna unit includes: the first dielectric substrate 11, the second dielectric substrate 12, the third dielectric substrate 13, the radiating structure 31 and at least one set of transmission units 20, the transmission units 20 comprising a first feed structure 21, a second feed structure 22 and a filter structure 23.
It will be appreciated that an antenna element may comprise multiple sets of transmission elements 20,1 of which only one set 20 is shown for ease of illustration.
The second dielectric substrate 12 is arranged between the first dielectric substrate 11 and the third dielectric substrate 13, the radiation structure 31 is arranged on one side of the first dielectric substrate 11 far away from the second dielectric substrate 12, the second feed structure 22 is arranged on one side of the second dielectric substrate 12 near the first dielectric substrate 11 or one side of the first dielectric substrate 11 near the second dielectric substrate 12, the filter structure 23 is arranged on one side of the third dielectric substrate 13 near the second dielectric substrate 12 or one side of the second dielectric substrate 12 near the third dielectric substrate 13, the first feed structure 21 penetrates through the first dielectric substrate 11, the second dielectric substrate 12 and the third dielectric substrate 13, and the first feed structure 21 is connected with the second feed structure 22 and the filter structure 23.
Optionally, the antenna ground 14 is placed on the side of the third dielectric substrate 13 remote from the second dielectric substrate 12.
The first feed structure 21 is for transmitting electromagnetic wave signals; the second feed structure 22 is used for coupling feed to the radiating structure; the filtering structure 23 is used for filtering.

The second feed structure 22 is used for coupling feed to the radiating structure.
Optionally, as shown in fig. 1, a specific metal pattern is covered on a side of the third dielectric substrate 13 close to the second dielectric substrate 12 or a side of the second dielectric substrate 12 close to the third dielectric substrate 13 to form a filter structure 23. The filtering structure 23 is used to change the transmission mode of the antenna to generate transmission zeros for filtering.
The antenna unit provided by the embodiment of the application has a simple structure, and can reduce the equipment size on the premise of realizing low-pass, band-pass, high-pass and band-stop filter characteristics by integrating the antenna and the filter, thereby having low cost, high stability and good filter characteristics.
In summary, the antenna unit provided in the embodiment of the present application includes: the device comprises a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a radiation structure and at least one group of transmission units, wherein each transmission unit comprises a first feed structure, a second feed structure and a filter structure; the second dielectric substrate is arranged between the first dielectric substrate and the third dielectric substrate, the radiation structure is arranged on one side, far away from the second dielectric substrate, of the first dielectric substrate, the second feed structure is arranged on the second dielectric substrate, the filter structure is arranged on the third dielectric substrate, the first feed structure penetrates through the second dielectric substrate and the third dielectric substrate, and the first feed structure is connected with the second feed structure and the filter structure; the first feed structure is used for transmitting electromagnetic wave signals; the second feed structure is used for coupling feed to the radiation structure; the filtering structure is used for filtering. By integrating the antenna and the filter, the size of the device is reduced, and the device has low cost, high stability and good filtering characteristics.
Compared with the scheme that the antenna unit and the filter are independently designed, the antenna with good filtering characteristics needs to be pressed for multiple times, has a complex structure, and greatly increases the cost of the antenna. The antenna unit in the embodiment of the application has the advantages that all components in the antenna unit are directly finished on the dielectric substrate, so that the structure is simple, the manufacture is easy, the PCB processing is convenient, the processing can be finished by only one press fit, the low cost is realized, the excellent filtering characteristic is realized, and the method has great significance for practical engineering application.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating comparison of filtering effects of a conventional antenna and a filtering antenna according to an embodiment of the present application. Assuming that the working frequency band of the filter antenna is 14GHz-14.5GHz, the filter antenna needs to filter 10GHz-13GHz, the transmission zero point is about 12.5GHz, and the filter characteristics of the filter antenna are shown in fig. 2: the filtering antenna works at 14GHz-14.55GHz, the gain is more than 5dB in the full frequency band, the antenna gain is less than-15 dB in 10GHz-13GHz, the full frequency band inhibition is more than 20dB, and the radiation zero is formed in 12.6GHz, so that the required filtering effect is achieved. The conventional non-filtering antenna has the gain smaller than 0dB and the suppression only 5dB at 10GHz-13GHz, and the filtering effect is far lower than that of the filtering antenna provided by the embodiment of the application.
With continued reference to fig. 1, a possible implementation manner is provided in the embodiment of the present application as to how to guarantee the performance of the antenna unit. The second feed structure 22 at least partially overlaps the projection of the radiating structure 31 onto the second dielectric substrate 12.
It will be appreciated that the size of the overlap area is related to the predetermined operating frequency.
Optionally, one end of the second feed structure 22 is connected to the first feed structure 21, and the other end of the second feed structure 22 is directed towards the geometric center of the projection of the radiating structure 31 onto the second dielectric substrate 12.
Referring to fig. 3, fig. 3 is a top view of an antenna unit according to an embodiment of the application. As shown in fig. 3, in one possible implementation, the filter structure 23 includes a first filter component 231 and a second filter component 232, and the first feeding structure 21 is connected to one end of the first filter component 231, and the other end of the first filter component 231 is connected to the second filter component 232.
The first filter assembly 231 and the second filter assembly 232 constitute a T-shaped filter structure.
In one possible implementation, the end of the first filter element 231 remote from the first feed structure 21 is in contact with the length L2 direction in the second filter element 232.
Alternatively, the first filter component 231 and the second filter component 232 are disposed on a side of the third dielectric substrate 13 adjacent to the second dielectric substrate 12 or a side of the second dielectric substrate 12 adjacent to the third dielectric substrate 13.
The first filter element 231 and the second filter element 232 may not be limited to a straight line, and may be a curve having an amplitude.
In one possible implementation, to enhance the filtering effect, the other end of the first filter element 231 is connected to the midpoint of the second filter element 232.
With continued reference to fig. 3, the length of the first filter element is a first length L1, the width of the first filter element is a first width W1, the length of the second filter element is a second length L2, and the width of the second filter element is a second width W2.
The first length L1, the first width W1, the second length L2 and the second width W2 are matched with a radiation zero of the antenna unit, and the radiation zero is used for indicating a frequency band to be filtered.
For example, as shown in fig. 2, the radiation zero point is 12.6GHz, and the filtering effect can be achieved on the frequency band of 10GHz-13 GHz.
It should be noted that, by adjusting the dimensions of L1, L2, W1 and W2 in the T-shaped filter structure, the radiation zero position of the antenna can be changed, so that in the antenna design process, it is required to ensure that the first length L1, the first width W1, the second length L2 and the second width W2 are matched with the radiation zero of the antenna unit.
With continued reference to fig. 3, in one possible implementation, the angle between the projections of the first filter element 231 and the second feed structure 22 on the third dielectric substrate 13 is the target rotation angle.
The target rotation angle is matched with a radiation zero point of the antenna unit, and the radiation zero point is used for indicating a frequency band to be filtered.
It will be appreciated that the rotation of the T-shaped filter structure around the first feed structure 21 may change the radiation null position of the antenna. The target rotation angle needs to be determined in advance in the antenna design process. The target rotation angle matches the radiation null of the antenna element.
In one possible implementation, when the number of transmission units 20 is greater than 1, the transmission units 20 are all distributed around the center point of the radiation structure 31.
For example, when the number of the transmission units 20 is 2, the rotation may be 90 °, 180 °, 270 ° based on the center point of the radiation structure 31.
When the number of the transmission units 20 is 3, the transmission units 20 may be circularly distributed around the center point of the radiation structure 31, and 3 transmission units 20 are rotated 120 ° around the center point of the radiation structure 31.
When the number of transmission units 20 is 3, the transmission units 20 may be unevenly distributed around the center point of the radiation structure 31, assuming that the angle of one of the transmission units 20 is 0 °, the remaining 2 transmission units 20 have 3 rotation combinations around the center point of the radiation structure 31, the first being 90 °, 180 °, the first being 90 °, 270 °, the first being 180 °, 270 °.
When the number of the transmission units 20 is 4, the transmission units 20 may be uniformly distributed around the center point of the radiation structure 31, and the 4 transmission units 20 are rotated by 90 ° around the center point of the radiation structure 31.
In one possible implementation, the geometry of the radiating structure 31 is circular, rectangular or polygonal.
Optionally, the first feed structure 21, the second feed structure 22 and the filter structure 23 are metal structures.
The characteristics (including relative permittivity, loss tangent, and thickness) of the 3-layer microwave dielectric substrate may be the same or different, and are not limited thereto.
Alternatively, the microwave dielectric substrate characteristics may affect the size, shape, area, etc. of the radiating structure 31 and the feed structure. For example, the dielectric constant is large, the radiating structure area is small, and the intersecting area of the second feeding structure 22 and the radiating structure 31 is small; the loss angle is large, and the gain of the antenna is reduced.
For easy understanding, the embodiment of the application also provides a side view of the antenna unit, as shown in fig. 4.
The embodiment of the application also provides a filter antenna, which comprises the antenna unit. In the scheme of the application, the number of the antenna units in the filter antenna is not limited.
